In a large bowl, combine peaches, corn, tomatoes, red onion, jalapeno, and cilantro. Gently stir in the avocado. Add the lime juice and season with salt and pepper. Gently stir and serve immediately.
Note-this salsa is great with chips, crackers, or served with chicken, fish, or pork. It is also a great topping for tacos, burritos, salads, tostadas, and enchiladas.
